e0“Photosynthesis was augmented by 6 % in winter and reduced by 7 % in summer, when light absorption in the top part of the canopy was increased by 25 %, while not changing light absorption of the canopy as a whole.”
e1“Simulations were performed with an FSPM of a greenhouse-grown tomato crop.”

Other claims from this paper (7)
- Intervention effect Increasing top-canopy light absorption by 25% augmented tomato canopy photosynthesis by 6% in winter.
- Observation Measured tomato leaf elevation angle, leaflet angle and leaflet arrangement were already optimal for light absorption and photosynthesis.
- Observation Leaf phyllotaxis had no effect on tomato light absorption or photosynthesis.
- Intervention effect Increasing tomato leaf length-to-width ratio by 1.5 increased light absorption and photosynthesis by 6–10%.
- Intervention effect Increasing tomato internode length from 7 to 12 cm increased light absorption and photosynthesis by 6–10%.
- Intervention effect Deeper light penetration improved tomato photosynthesis at summer light intensities, but not at winter light intensities.
- Intervention effect A spacious tomato ideotype with long internodes and long, narrow leaves increased crop photosynthesis by up to 10%.
